Cell cover: Eat more when you're delicious! Scientists have discovered brain secrets about eating and eating nonstop.

The latest issue of Cell, a leading academic journal, has a cover that's so cute that it's foul! See the mice sitting in chocolate, doughnuts, puffs, cakes, auspicchilds, one hand grasping the favorite snacks, one hand holding a glass of pain, people can not help but exclaim: Oh, this is not exactly me on the sofa? As if I heard a voice saying: Eat more! The sound of food, scientists understand! In the cover study, scientists from Janelia Research Campus at the Howard Houston Institute of Medicine (HHMI) studied what this constant appetite is all about.
in mice, they found a group of special neurons in their brains, specifically after eating and drinking good food, encouraging animals to continue eating, drinking and not stopping.
of course, eating, drinking and drinking is not an easy thing to do.
Instinct drives us to forage when we are hungry and thirsty, to feel and decide whether to eat or not to eat when we find food or water, to see through the eyes, nose smell, mouth to taste, to a certain extent to produce satisfaction (or not to eat), and so on.
therefore, it is a challenging task to clearly identify the various signals that come together in the brain about eating and drinking and to identify the neural loops that control different eating and drinking behaviors.
, the team, led by Dr. Scott Sternson, first looked for brain regions in the brains of mice that coexisted with hungry and thirsty nerve loops.
they noted that a group of glutamate-energy neurons, known as periLC neurons, were involved in eating and drinking, a gathering point for hunger and thirst, near the blue spot of the brain's brain.
then, to study the function of these nerve cells, the team developed a technique that allows mice to move freely while observing the activity of periLC neurons in the brain's brain through a microscope.
, the study's first author, said addressing the technology was key to the study.
the new imaging technique, the researchers found that periLC neurons react specifically only when mice start eating and drinking, and that animals eat and drink longer.
these neurons were less active than usual when the animals ate or ate water.
inhibits the activity of these neurons, which in turn encourages mice to eat and drink longer as if something was particularly delicious.
More interestingly, if the mice were particularly hungry or thirsty and ate bland food and water, the neurons reacted particularly strongly, similar to what they normally eat when they liked something particularly sweet.
other words, when hungry to eat particularly fragrant, when thirsty boiled water is also a little sweet, it seems that there is a group of neurons to credit.
researchers say understanding the function of this particular group of neurons could help to better understand how the brain pursues dietary pleasures and may also provide new treatment ideas for health problems that can't be understood, such as obesity and diabetes.
and eat, the next time I eat delicious and delicious, mouth can not stop, perhaps you can also explain to yourself: not I greedy, but I have some neurons in my brain more sensitive! ()
